MERC
From ThreeA Wiki
MERC is a colorway that spans a number of robots in the WWR and WWRp lines. The name comes from the word "mercenary." The color scheme tends to be primarily black, however, Ash has confirmed on 3A Forums that the mercenaries in the WWR Universe individualize their bots so no two MERC robots would look the same. Also see the Dutch Merc colorway.
